Theresa is constantly by Vanessa's side while she waits for news. Theresa was also very supportive when Vanessa had to have a mastectomy several years earlier and met James Wilson while her sister was being treated.

When Vanessa's oxygen levels started to drop and Vanessa refused further treatment, Vanessa still stood by her even though she disagreed.

When Vanessa's ex-boyfriend Bobby showed up, Theresa was very angry, but Wilson explained that Bobby once before convinced Vanessa to accept treatment and he might be able to do it again.
